Super-Resolution Neural Operator

This repository contains the official implementation for SRNO introduced in the following paper:

Super-Resolution Neural Operator (CVPR 2023)

Our code is based on Ubuntu 18.04, pytorch 1.10.2, CUDA 11.3 and python 3.9.

Train

python train.py --config configs/train_edsr-sronet.yaml if you want to change encoder, please modify the yaml file

model:
  name: sronet
  args:
    encoder_spec:
      name: edsr-baseline ## or rdn
      args:
        no_upsampling: true
    width: 256
    blocks: 16

Test

Download a DIV2K pre-trained model.
